I have an XML fragment that I am trying to compile using JAXB. The compilation executes successfully but there are some differences between the java files generated by JAXB when compared to XMLBeans. Here is the XML fragment:

<simpleType name="MyDataType">
<restriction base="xsd:string">
<enumeration value="Text"/><!-- enum const = 0 -->
<enumeration value="Integer"/><!-- enum const = 1 -->
<enumeration value="Float"/><!-- enum const = 2 -->
<enumeration value="Boolean"/><!-- enum const = 3 -->
<enumeration value="TimeStamp"/><!-- enum const = 4 -->
<enumeration value="Code"/><!-- enum const = 5 -->
<enumeration value="MultiLanguageText"/><!-- enum const = 6 -->

JAXB will generate the following class:

@XmlType(name = "MyDataType", namespace = "")
public enum MyDataType{

private final String value;

MyDataType(String v) {
value = v;

public String value() {
return value;

public static MyDataType fromValue(String v) {
for (MyDataType c: MyDataType.values()) {
if (c.value.equals(v)) {
return c;
throw new IllegalArgumentException(v);

XMLBeans would apply an ordinal to the elements like so:

public interface FlexFieldDataType extends org.apache.xmlbeans.XmlString
public static final org.apache.xmlbeans.SchemaType type = (org.apache.xmlbeans.SchemaType)
org.apache.xmlbeans.XmlBeans.typeSystemForClassLoader(FlexFieldDataType.class.getClassLoader(), "schemaorg_apache_xmlbeans.system.s463C563221D006C73594BDAF6D050EA7").resolveHandle("flexfielddatatypeb902type");

org.apache.xmlbeans.StringEnumAbstractBase enumValue();
void set(org.apache.xmlbeans.StringEnumAbstractBase e);

static final Enum TEXT = Enum.forString("Text");
static final Enum INTEGER = Enum.forString("Integer");
static final Enum FLOAT = Enum.forString("Float");
static final Enum BOOLEAN = Enum.forString("Boolean");
static final Enum TIME_STAMP = Enum.forString("TimeStamp");
static final Enum CODE = Enum.forString("Code");
static final Enum MULTI_LANGUAGE_TEXT = Enum.forString("MultiLanguageText");

static final int INT_TEXT = Enum.INT_TEXT;
static final int INT_INTEGER = Enum.INT_INTEGER;
static final int INT_FLOAT = Enum.INT_FLOAT;
static final int INT_BOOLEAN = Enum.INT_BOOLEAN;
static final int INT_TIME_STAMP = Enum.INT_TIME_STAMP;
static final int INT_CODE = Enum.INT_CODE;

* Enumeration value class for com.sumtotalsystems.sumtotal7.sumtotalbo.FlexFieldDataType.
* These enum values can be used as follows:
* <pre>
* enum.toString(); // returns the string value of the enum
* enum.intValue(); // returns an int value, useful for switches
* // e.g., case Enum.INT_TEXT
* Enum.forString(s); // returns the enum value for a string
* Enum.forInt(i); // returns the enum value for an int
* </pre>
* Enumeration objects are immutable singleton objects that
* can be compared using == object equality. They have no
* public constructor. See the constants defined within this
* class for all the valid values.
static final class Enum extends org.apache.xmlbeans.StringEnumAbstractBase
* Returns the enum value for a string, or null if none.
public static Enum forString(java.lang.String s)
{ return (Enum)table.forString(s); }
* Returns the enum value corresponding to an int, or null if none.
public static Enum forInt(int i)
{ return (Enum)table.forInt(i); }

private Enum(java.lang.String s, int i)
{ super(s, i); }

static final int INT_TEXT = 1;
static final int INT_INTEGER = 2;
static final int INT_FLOAT = 3;
static final int INT_BOOLEAN = 4;
static final int INT_TIME_STAMP = 5;
static final int INT_CODE = 6;
static final int INT_MULTI_LANGUAGE_TEXT = 7;

Is there anyway I can achieve this behavior using JAXB? The ordinals are references throughout the client code and it would be nice to preserve this behavior ...
It's just a flesh wound! Or a tiny ad:
